I downloaded Energia 1.6.10e18
I am programming an msp430g2452
I am using LanchPad MSP-EXP430G2 to program my part (on a custom board via spi-by-wire)
I am running Energia on Windows 7
I ran update on Energia MSP430 boards via Boards Manager to version 1.0.2
When compiling I get the following errors:
In usi_spi.cpp I had to change a couple of instances of spi_tx to spi_send (fixed code below):
void spi_transmit16(const uint16_t data)
{
spi_send(data & 0xFF);
spi_send((data>>8) & 0xFF);
}
void spi_transmit(void *buf, uint16_t count)
{
uint8_t *p = (uint8_t *)buf;
if (count == 0) return;
while(count){
spi_send(*p++);
count--;
}
}
Code then compiles, but doesn't run properly. The warnings are:
To fix the clock problem, in msp430g2452.h I had to add a section defining the TLV data (added at line 760):

Now code compiles and runs properly on the processor. I have not tested out SPI data yet, so I'm not 100% that it works.
Speedbug78 got a reaction from Fmilburn in File Changes to Support MSP430G2452 and SPI
